摘要

研究目的：過重與肥胖會增加國人罹患疾病與不良預後的風險，飲食行為在體重管理扮演重要角色，食物渴望會促使個體產生較多不利健康的飲食行為。本研究旨在修訂中文版食物渴望特質量表（Food Craving Questionnaire-Trait, FCQ-T）之信效度，作為研究與臨床評估工具。研究方法：本研究招募361位與245位參與者填寫網路與紙本問卷，分別進行研究一的項目分析、探索性因素分析；以及研究二的驗證性因素分析，並檢驗信度、效標關聯效度。量表包括：基本資料表、食物渴望特質量表、健康相關的飲食與運動行為自我效能量表（簡稱自我效能量表）、情緒飲食者量表、嘴饞量表。研究結果：中文版食物渴望特質量表共23題，包含四個分量表：情緒型渴望、失控型渴望與內疚、線索誘發型渴望與正向預期、認知型渴望，可解釋65.05%的總變異量。全量表內部一致性信度（Cronbach's alpha）為.95，FCQ-T與自我效能量表呈顯著負相關；FCQ-T與情緒飲食者量表、嘴饞量表、體重、身體質量指數呈顯著正相關。研究結論：中文版食物渴望特質量表具有良好的心理計量特性，可供未來研究與臨床評估之工具。

Purpose: In Taiwan, overweight and obesity are linked to increased risk of disease and poor prognosis. Eating behavior plays an important role in weight management, and food cravings can lead to unhealthy behavior. The purpose of the present study is to revise the Chinese version of the Food Craving Questionnaire-Trait (FCQ-T) and to examine its reliability and validity for application in future research and clinical practice. Methods: We recruited 361 and 245 participants for 2 studies. They filled out the web-based questionnaires or paper questionnaires, including the FCQ-T, Self-Efficacy Scale for Health-Related Diet and Exercise Behaviors (SES), Emotional Eater Questionnaire (EEQ), and Grazing Questionnaire (GQ). Study 1 entailed item analysis and exploratory factor analysis. Study 2 entailed confirmatory factor analysis, and reliability and criterion-related validity testing. Results: The FCQ-T included 23 items with 4 subscales: emotional craving, uncontrolled craving and guilt, cue-induced craving and positive anticipation, and cognitive craving. The measure accounted for 65.05% of the variance. The internal consistency reliability (Cronbach's alpha coefficient) of the FCQ-T was .95. A negative correlation was found between FCQ-T and the SES; the positive correlations were found between FCQ-T and EEQ, GQ, weight, and body mass index. Conclusions: The Chinese version of FCQ-T has good psychometric properties for research and clinical practice in Taiwan.
